Alright Tamiya Grasshopper owners, listen up! If your RC car isn't running as smooth as it used to, these FastEddy bearings are exactly what you need. This kit comes with 10 sealed bearings specifically designed for the Tamiya Grasshopper XB (that's model #57746 for those keeping track). You get one 5x8x2.5mm bearing and nine 5x11x4mm bearings - basically everything you need to replace all the worn-out bearings in your ride. These aren't some cheap knockoffs either - they're quality sealed bearings that'll make your Grasshopper run quieter, smoother, and faster than ever. Installation is pretty straightforward if you're comfortable working on your RC car, but here's the important part: double-check your specific model before ordering! Sometimes manufacturing dates or aftermarket upgrades can change bearing sizes, so make sure these match what you actually need. If you're not sure, just message the seller - they're super helpful about compatibility questions. Once you get these installed, you'll notice the difference immediately. Less friction means more speed and longer run times, plus your car will just feel more responsive. It's one of those upgrades that seems small but makes a huge difference in how your Grasshopper performs. Whether you're racing competitively or just bashing around the backyard, fresh bearings are always a good investment for keeping your RC car in top shape.
